HENRY A. GARVEY, OF NEWV YORK, N. Y.

MACHINE FOR MIXING MORTAR.

SPECIFICATION forming part of Letters Patent No. 438,805, dated October 21, 1890.

Application filed December 13, 1889. Serial No. 333,678. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. GARVEY, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and useful and Improved Machine for Mixing Mortar, of which the following is a full, clear, and exact description.

My invention is designed particularly for mixing or making mortars for use by builders, and doing it thoroughly and cheaply.

The invention consists in novel features of construction, and also in certain combinations of parts of the apparatus for carrying out various principles of the devices, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of the mixing-machine, showing three groups of hoe attachments connected as a Whole. Fig. 2 is a transverse sectional elevation of the mixing-machine. Fig. 3 isalarger vertical sectional View of the hoe attachment F than appears in Fig. 1, and is given for clearness. Fig. 4 is an outline plan of mixer, showing a group of three transverse rows of quadruple curved-faced hoes, also showing the changes alternately in the alignment of the faces of the hoes, which, as represented in Fig. 3, show a long and a short projecting face, the dotted line indicating the alternate one.

Fig. 1 represents a tank placed on standards A sufficiently high to'let the dumpingdoors B swing clear.

0 represents a group of three independent transverse rows of hoes, each row bolted to a separate cross-beam by means of shanks B, one of which is attached to each hoe, said cross-beam terminating at both ends in axles to which are fitted flanged wheels which rest on tracks shown in Fig. 1 and by sectional View in Fig. 2. Said group of three transverse rows of hoes are secured in their re spective positions by means of longitudinal bars on extreme ends of axles in such a manner as to admit of the removal of a group for repairs. The number of groups of hoes used depend on the amount of work required of a mixer.

F is a hoe attachment having two exterior faces with downward and outward concave curves designed to give a lifting and rolling motion to material under treatment. F also has two interior curved faces formed by the flanges S.

F in Figs. 1 and 3 show from a center line, assumed to be dropped from center of shank H to base of hoe, a greater projection at bottom of one exterior curved face. This formation tends to force the mortar in front of a group in the shape of a broken wave, and also leaves a side space between the long and the short faces of the hoes when placed with alternate projections, as indicated in Figs. 1 and 3 by dotted lines and in Fig. 4. by the arrows.

The front View of hoe in Fig. 2 shows two spaces in the face thereof, which spaces are duplicated on opposite face. These spaces relieve the pressure on the alignment of hoes while in motion by allowing a certain amount of material to squeeze through, and, in conjunction with the spaces at sides formed by the long and the short faces of hoes in juxtaposition, supply interior faces of hoes with material to treat.

The shank H forms an important feature of hoe by serving as a disintegrator for p1as tering-hair, which is applied while in a moist state and is lumpy and detrimental until separated. The said shanks, from their num-, ber in a group, form a coarse screen, which efiectually separates the hair, while their upper ends form aconnection with the cross-beam by being secured thereto.

Owing to the natural consistency of mortar, the movement of the machine as required is necessarily slow and could be given by any method chosen which gives a backward and forward motion. The working of the material is continued until the components become a homogeneous mass, when the doors B are 9 1. A quadruple cnrved-faced hoe having two exterior and two interior faces, the exterior faces having curves of a concave character with different sweeps, While the interior faces, formed by the backs of the exterior faces and the flanges S, show irregular curves, the four faces showing different distances from a center line dropped from shank H to base-line of hoe, substantially as set forth.

2. In a machine for mixing mortar, the combination of the four-faced hoe formed in transverse alignment, as shown in Fig. 2, with the long and the short projecting faces placed al ternately, as shown in Fig. 4, and the shanks
